(GRANTED UNIIER THE PROVISIONS oFTHE AcTfor' 'Manon 3, 192i, 41 STAT. L., 1313.)v` f" To all whom t may concern.' n

Be it known that I, ARTHUR .HAMMOND SHTPLEY, subject of the King of vGreat Britain, residing at Leicester,in the county of Leicester, England, have invented certain i new and useful Improvement in or Relating to Brush-.Making Machines, of 'which the following is a specification, reference being had therein to the accompanying drawing, l0 and for which I have applied for Letters Patent of Great Britain May 21, 1917, which application has matured into British Patent No; 115,889, granted August th, 1918.

- This invention relates to brush-making 15 machines and concernsv more particularly machines used for the purpose of drilling or boring stocks, heads or backs of brushes preparatory to the insertion of tufts of bristles therein. lWhile the invention f isI chiefly intended for use in connection with brush-drilling machines, it isnot necessarily limited to this kind of machine as it may y admit of application to other machines eniployed in brush-making, such for instance as filling machines. For thepurpose ofthe present description however, it will be hereinafter referred to in connection with a brush-drilling machine.

The invention has reference tomachiiies f of the class above mentioned `wherein provision is made whereby the position of the brush head, back or stockl (hereinafter referred to as the stock) may be changed relatively to the normal centre or centres about which it is'moved to produce radiating -holes as is necessary when the tuftsy of bristles are to have whaty is known asspread, such change in position being eiieoted without removal of the stock from the holding means.l

40 In some kinds of brushes, it is desirable to insert the tufts in groups or panels arranged i in different positions onV the`l stock, and in order that the tufts in each group or` vpanel V shall have the same spread or` relative angle scribed, it is necessary to change the position of the stock relatively tothe normal centre or' centres' from which vthe holes radiate soy that the holes'in each -groupmay be drilled the purpose of expediting thev operationof the-machine where such change of position Vof the stock fis necessary, the present' invention Aprovides means whereby the transport BRUSH-MAKING MACHINE y of inclination, as will bel hereinafter d e-lto radiate from said centre or centres.l Forl vorfbodily movemento'f the stock-maybe;

It is to be understood that the invention y embodiment illustrated-Jin Figurest'l, 2 and 3 y as such'einb'odiinent is shown andjrwillsbe y hereinafterdescribed merelybyjway of eX-* ample; other constructionalj arrangements:y

`coming within'thevs'copeof the` invention will also be described.' Y- y The form of brush-drillinginachinelshown' f in Figure 3' is aI-convenientfone fortheipurpair of holding members 9relatively adjustlcured.

able bymeansfof a screw 10 to clamp upon and hold the stock S. In the form shown, the holding members 9 are provided with dogs 11, but the workgholder may take other .for/ins, the present invention concerning not so much theI construction of the work holder as the .arrangement and actuation of the same, in a manner whereby it may be rapidly moved from one position to another.

vThe work holder is mounted upon the rocking and oscillating frame which also' carries the templet .or pattern board 12 (Figure 3). This frame in theparticular machine shown, comprises side rods 13 which by-means of fittings 14, support transverse rods 15 (Figures 1,72 and 3) which carry the Workgv holder said fittings also beingjprovided with bosses 16 in which the rods i17, to which the templet 12 is attached, are rigidly se- By means of .further fittings 18 (Figure 3),. through which the side rods 13 are adjustable, the fore part of the frame constituted by the parts 12, 13, 14, 15, 16 and 17 already referred to and which form a rigid structure, can rock i. e. be moved up and down, upon a horizontal axis 19 formed by pins 20 on the opposite ends of a cross barz21, the fittings being adapted toturn on the pinsv20. They cross bar 21 is attachedy to two rods22 which are adjustable through bearings 23 on a bearing plate 24 mounted by means of. a pivot pin 25 on a carriage or trolley. 26y arranged to run upon wheels along a suitable track 27 on atrack plate 28 fas' .tenedy upon the bed 1. The pivot pin 25 forms the vertical aXis upon which the work carrying frame as a whole can turn as indicated bythe dotted lines it being understood that for obtaining the vertical spread of the holes thefore part of the frame is rocked onl the horizontal axis 19, while for obtaining the horizontal spread ofthe holes in the stock, the whole frame is oscillated upon the vertical axis 25.

For conveniencer the rocking and oscillating work carrying frame is shown mountedupon the movable carriage or trolley 26. which formsthe ,subject of my copending application ySerial No. 499,474, but

1 is obvious that it may be otherwise mounted as this feature does not'form part of the present invention. t

Indrillingtlie ystock vS the latter is drawn on to the drill 5 by pulling forward the work carrying'frame which longitudinal movenient is permitted by the travel of the carriage 26, the position of each hole to be drilled being determinedby corresponding holes in the templet 12 said holes being used in conjunction with a fixed pointer pin 29 mounted in a standard 30 upon the bed 1. After each hole is drilled the work carrying frame is moved on either or both the.v axes 19, 25 to bring other holes into line with the pin 29.

As illustrating the purpose for which the present invention is to be employed, a convenient example of a brush stock having a paneled arrangement of holes is shown diagrammatically in Figures 5 to 8. Figure 5 is a face view of the stock S `and the circles represent the positions of the holes. Fignre 6 isa vertical side view of the same stock,

the radiating centre lines indicating the spread or the vertical row of holes on line a-a of Figure 5. Figure 7 is a longitudinal section on line lZi--i of Figure 5, the centre lines here indicating the spread or radiations of the horizontal row of holes. Figure-8, to which reference will be made shortly, Ais a longitudinal section on liney c-c of Figure .5.

In the arrangement of holes represented in Figure 5 the inarginalrows 31 and 32 .are i drilled to radiate from a line which passes through tlie centie 33 ofthe stock, this being clearly shown in Figures 6 and 7 which Vil1idicate the verticaly soread and horizontal spread respectively. n drillingthese marginal'holes the templet or pattern board.

represented in Figure 4 is used, the stocks` is positioned centrally in the work carryingl frame as shown by full llines in Fignre 3 and the outer series of holes 34 and in the templet are brought in succession on to th pin 29.

Referring again toFigure 5 the holes'coinposing the two separate groups or panels situated withinvv the linesd and e whileliaving the same vertical spread as the holes in the vertical rows 32 are required to have a different spread from the horizontal rows of holes 31, for instance it maybe desired that the holes in each group (Z, e shall radiate from a. line passing through the centres 36, 37 of the respective groups as represented in Figure 8 where the centre lines indicate the angles lof sprea'd or radiations ofthe holes along tlieline c--c of Figure 5. lt will be noticed f by referring to Figure 8 that although the radiations of the holes in one of the groups or panels is identical with those of, the holes in the other group, the radiations of. the

holes in both groups are distinct friointliosei ofthe holes in the marginal rows 31A setout in Figure 7.

T opproduce the separately grouped,radiaf,` tions referred to the same templet 12 is eni ployed this being provided with ay centrally.:

iso

disposed group of holes 38. This single group of holes enclosed within the line fis used to determine the positions of the holes in both the groups d and e but in order to obtain the desired horizontal spread of the holes in each of said latter groups, the stock S is altered in position in the frame by being transported bodily whereby the centre of each panel is brought into line with the normal centre of the frame which is of course the line from which holes positioned on either side of it vwill radiate. Thus by transporting the stock first one series and then the other series of holes composing the groups d and e may be formed by means o-f the holes in the group 38 in the templet.,v

For the transportation of the stock S in the manner described, thel work holder is movable bodily in the frame to which end, in the embodiment shown in Figures 1, 2 and 3, the two clam devices 8 are connected by bars 39, 40 (Figures 1 and 2) and are freely slidable to and vfro along lthe rods 15 before referred to. The movement ofy the work holder i. e; the complete structure formed by the clamp devices 8 and the bars 39, 40, along the rods 15, is effected by means of a hand lever 41 pivotally attached at 42 (Figure 1) to the bar40 its lower end having ivotal connection with one end of a llink 43. he opposite end of the link is fulcrumed at 44 ona rigid support45 and it will kbe seen that by simply turning the hand lever 41 in one direction or thel other from the perpendicular position the work holder will be at once shifted in the same direction along the rods 15. In F-igures 1 and 3 the work holder is shown in the normal central position by full lines such position being suitable for forming the mar inal holes 31, 32 (Figure 5) in stock S. n the same figures the work holder is shown by dotted lines in the position it would be transported to for holding the stock while the holes in group Z- were being formed, the dotted lines in Figure 3 indicating also the position yof the work carrying frame and the stock in relation to the drill forming the innermost holes 46 of the group d. Y

For holding the wo-rk holder in its respective positions a spring controlled detent or catch 47 (Figures 1 and 2) on the hand lever 41 co-operates with an arcuate plate 48 situated behind the lever and secured to the work holder by the screws ,49 which attach the bar 39 to the clamp devices 8. The detent or catch 47 engages with notches 5() in the edge of the plate 48 to determine the proper position of the work holder and maintain it therein. The catch is disengaged from the notches by being turned on its pivot 51 (Figure 2).

Inorder that the distance between 'the connected clamp devices 8 may be varied to suit brush stocks of different length, the connecting bars 39,y 40 and the yplate 48 are each provided near their'- ends with a series of Aholes 52 through any onefof whichthe ment of holes'such as described with refers enceV to Figures 5 to 8*as it will be apparentv that by means of a movable work holder and.

means for actuating the same such as shown in Figures 1 and 2, the stock may be readily and accurately transported bodily, without removal from the work holder, to bring any part throughout the length of the stock into position onthe -centre linejfor the formation of holes in said part which radiate from the centre line thereof, .the arcuate plate 48..

having notches suitably disposed `in its edge to define the positions of the rwork holder on the frame.'l w
